Header Name of the listview?

Hi,

I have already tried this but the program were forced to exit.

////////////////////////////////////////////////////////
////////////////////////////////////////////////////////

CHeaderCtrl* pHeader = (CHeaderCtrl*)wndList.GetDlgItem(0);
HD_ITEM headerinfo;
headerinfo.mask = HDI_TEXT;
      
if (!(pHeader->GetItem(0,&headerinfo)))
  AfxMessageBox("ERROR");

TRACE("HEADER NAME = %s\n", headerinfo.pszText);

////////////////////////////////////////////////////////

What errors had I made?

Thanks for your opinion!!!

Retrieving the column caption


CString Caption; // will recieve the caption

// retrieve the header control see "The header control"
CHeaderCtrl* pHeader = (CHeaderCtrl*) m_listctrl.GetDlgItem(0);
int nMaxHeaderLength=100, // or whatever you need
    nColumnIndex;         // starts with zero, remember to initialize!

// fill the HDITEM structure
HDITEM HdItem;
HdItem.mask = HDI_TEXT; // just get the text
HdItem.pszText = Caption.GetBuffer(nMaxHeaderLength);
HdItem.cchTextMax = nMaxHeaderLength;

// retrieve the data
pHeader->GetItem(nColumnIndex, &HdItem);

// release the Buffer and finish
Caption.ReleaseBuffer();

TRACE("The caption of the Heading Number %i is :%s\n", nColumnIndex, Caption);

you need to fill in your HDITEM more as proskig has suggested

I don't think you have to get a pointer to the HeaderControl to get the header name. Instead use CListCtrl::GetColumn() to accomplish this task.

Here is the example:

CString strHeaderName;
int nHeaderLength = 100;

lvc.mask = LVCF_TEXT;
lvc.pszText = strName.GetBuffer(nHeaderLength);
lvc.cchTextMax = nHeaderLength;
m_listctrl.GetColumn(i, &lvc);

strName.ReleaseBuffer();

Correction:

CString strHeaderName;
int nHeaderLength = 100;

lvc.mask = LVCF_TEXT;
lvc.pszText = strName.GetBuffer(nHeaderLength);
lvc.cchTextMax = nHeaderLength;
m_listctrl.GetColumn(0, &lvc);

strName.ReleaseBuffer();

lvc.pszText will contain the name of the Header of column 1.
